grumppa, are you suggesting that men's "needs" as you put it have to be met, either by prostitutes or dumb animals if they aren't being met elsewhere? The fact your post comes immediately before Devorgilla's post about the rights of the partners of men or women who use prostitutes is one of life's little ironies isn't it.
Prostitution isn't a victimless crime, much as many of us would like it to be. those of us who have helped pick up the pieces when the lives of sex workers lead to their children being neglected, exposed to stuff they shouldn't have to see or know about or worse, become embroiled into the sordid trade itself are more than well aware of that.
I apologise for not seeing the joke about men's needs and the use of animals to satisfy them.
